Background

Sewage treatment is a process of purifying sewage to enable the sewage to meet the water quality requirement of drainage, is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, medical treatment, catering and the like, is classified according to sewage sources, and is generally divided into production sewage treatment or domestic sewage treatment.

The Orbal oxidation ditch process can be provided with three ditches, namely an outer ditch, a middle ditch and an inner ditch, the volume ratio is generally 50:33:17, the dissolved oxygen concentration is controlled to be 0mg/L, 1mg/L and 2mg/L respectively, the process is mainly set aiming at no distribution of rain sewage and unstable inflow of urban sewage, can generate simultaneous nitrification and denitrification to a higher degree, has a better denitrification effect, and can effectively solve the problem of unstable inflow of rural sewage.

The biological multiplication process is a novel sewage treatment process of German utility model, short-cut nitrification/denitrification is realized by adopting low dissolved oxygen (usually 0.3-0.5 mg/L), high sludge concentration (usually 5-8 g/L) ensures high efficiency and continuous stability of treatment, the biological multiplication process has high-efficiency biological denitrification and good dephosphorization effect, and the biological multiplication process has the advantages of small maintenance workload, small occupied area, low investment and operation cost.

The siphon backflow technology is characterized in that the backflow is caused by the reduction of the pressure of the water supply end of the water supply system or the generation of negative pressure (vacuum or partial vacuum), and the siphon backflow technology has no power.

The large-specific-power circulating dilution technology is used for circulating a mud-water mixture in a pool body in a biological multiplication process, wherein the circulating flow is dozens of times or even thousands of times of the inflow, and pollutants in a water body are gradually degraded by microorganisms along with the circulation of water flow, so that the pollutant concentration is lower at the tail end of the circulation, the pollutant concentration in the inflow is rapidly reduced, the microorganisms are effectively prevented from being impacted, and a stable water environment is provided for the growth of the microorganisms.

The micro-mixing and dense aeration effectively controls the concentration of dissolved oxygen and sludge, so that the shortcut nitrification and denitrification can be smoothly realized, the energy is saved, and the residence time of the system is reduced. In addition, the high sludge concentration improves the shock load resistance of the system.

The MBBR technology improves biomass and biological species by adding a certain amount of suspension carriers, thereby improving the treatment efficiency. As the density of the filler is close to that of water, the filler is completely mixed with the water during aeration, and the environment for the growth of microorganisms is three phases of gas, liquid and solid. The collision and shearing action of the carrier in water makes air bubbles finer, and the utilization rate of oxygen is increased. In addition, each carrier has different biological species inside and outside, anaerobic bacteria or facultative bacteria grow inside, aerobic bacteria grow outside, each carrier is a micro-reactor, and nitrification reaction and denitrification reaction exist at the same time, so that the treatment effect is improved.

An MBR membrane bioreactor, which replaces a secondary sedimentation tank at the tail end of the traditional biological treatment technology with a membrane component, keeps high activated sludge concentration in the bioreactor, improves the organic load of biological treatment, thereby reducing the occupied area of sewage treatment facilities and reducing the amount of excess sludge by keeping low sludge load. Mainly utilizes the membrane separation equipment immersed in the aerobic biological tank to trap the activated sludge and macromolecular organic matters in the tank. The concentration of activated sludge (MLSS) in the membrane bioreactor system can be increased to 8000-10,000 mg/L or even higher; the sludge age (SRT) can be prolonged to more than 30 days.

The hollow winding process is formed by the processes of extrusion molding, shaping and mechanical winding, has the characteristics of corrosion resistance, high strength, heat preservation, noise prevention, energy conservation and environmental protection, and is favorable for the generation and culture of rhodobacter in the sewage treatment process.

Therefore, it is very extensive to develop an integrated sewage treatment apparatus combining any of the above processes.
